Application filed November 30, 1923. Serial No. 677,760.

T 0 all 10 ham it may concern:

Be it known that I, JOHN RoBnRrWATrs, trading as John Watts, LambertWorks, Lambert Street, Sheffield, England, cutlery manufacturer, and aBritish subject, have invented a new and Improved Scissors Sharpener, ofwhich the following 1s a full, clear, and exact description.

This invention relates to a sharpening device and has particularreference to a device for sharpening scissors.

The outstanding object ofthe present invention is to provide means forfacilitating the sharpening or re-sharpening of the blades of a pair ofscissors which insures the proper relation of the blades to thesharpening element whereby the sharpening operation may be accomplishedby persons totally unskilled or unfamiliar therewith.

As a further object the invention contemplates a sharpening "device ofthe character set forth which is strong, durable and simple in itsconstruction, inexpensive to manufacture, and which is thoroughlyreliable and highly efficient in its purpose.

The invention still further contemplates a.- sharpening device includinga guide means for properly associating the scissors blades with thesharpening element and in which the said sharpening element is movableto dispose a new surface in the presence of the blades in order toinsure even wear on the sharpening edge thereof.

With the above recited and other objects in view, the invention residesin the novel construction set forth in the following specification,particularly pointed out in the appended claims and illustrated in theaccompanying drawings, it being understood that the right is reserved toembodiments other than those actually illustrated herein.

to the full extent indicated by the general meaning of the terms inwhich the claim is expressed.

In the drawings Figure 1 is'a perspective view illustrating the devicein use.

Fig. 2 is a cross sectional view therethrough.

Fig. 3 is a fragmentary side view thereof.

Referring to the drawings by characters of reference, the deviceincludes a base 10 preferably provided with a felt bottom lining 11. Astrip of material bent in inverted U-shaped form to provide spacedparallel walls 12 and 13 connected by a bight 14 at its upper endprojects upwardly from the base. The lower end of the wall 12 is formedwith a plurality of anchoring lugs 15 which are anchored in the uppersurface of the base. The opposite wall 13 is provided with an invertedlateral U-shaped extension 16 which embraces the parallel superposedends 17 of a handle 18. Fastening screws 19 are passed through thealigned openings in the ends '17 and the U-shaped extension 16, saidfastening screws being anchored in the base 10. A sharpening element 20preferably consisting of a disk of carborunduin or any other suitablematerial is secured on a shaft 21 journaled in the walls 12 and 13 forrotation. One end of the shaft is provided with a knurled manipulatingknob 22 for effecting rotation of the shaft and sharpening element,while the opposite end is provided with a reduced portion 23 which isupset over a washer 24 whereby the shaft is retained in place. In orderto prevent accidental rotation of the shaft and sharpening element, apair of spring elements 25 having radially projecting arms 26 and whichare centrally apertured to receive the shaft 21 are interposed betweenthe walls 12 and 13 and the opposite faces of the sharpening element.bight portion of the inverted U-shaped strip is slotted downwardly andinwardly at an angle as at 27 so that said slot intersects the path ofmovement of the periphery of the sharpening element 20 and providesmeans for positioning and guiding the blades B of the scissors S duringthe sharpening operation.

In use and operation the user grasps the handle 18 in the left hand forholding the base 10 in a steady position on its support ing surface. Thescissors with the blades in opened position are grasped as illus tratedin Fig. 1 and one of the blades is inserted in the slot 27 until thecutting edge engages with that portion of the periphery of thesharpening element 20 which registers therewith. By exerting a pressureon the blade and drawing the same back and forth across the periphery,the cutting edge of the blade will be sharpened at the appropriateangle. In order to insure even wear on the periphery of the sharpeningelement, the knurled knob 22 is manipulated to present a new surfacewithin the slot 27 after each sharpening operation.

I claim:

The

A scissors sharpener comprising a base, a strip of material bent into aninverted U-shape mounted on said base and provided strip With the pathof movement of the periphery thereof intersected by the slot, meansextending exteriorly of the U-shaped 10 strip and connected With thesharpening element for rotating the same, ahandle memher having anangularly disposed terminal and a lateral inverted U-shaped extensionfrom one of the Walls of the U-shaped strip overlying the angular bentterminal of the handle, and fastening elements extending through saidextension and the handle terminal and anchored in the base.
